So I can't sleep and my mind began to wander. I've been low-key obsessed with Obey me and was thinking about Barbatos since his song is stuck in my head, and I had a thought.
Basically my brain went "haha his hair is kinda like Jade's but the colors are swapped"
But then I began to look into it.
As you can see here, they have similar color pallets for their hair. But the styles are similar as well, specifically, with their hair strands.
Proof:
But it goes deeper then just hair.
Jade is often compared to Sebastian Michaelis from Black Butler due to his Demon-Butler-like attitude. He listens to orders, a not so secretly dangerous opponent, and is incredibly cunning.
But do you know who else is a demon butler and shared these traits?
Barbatos
That fucker is Barbatos in disguise, he's looking for MC so he can drag them to the Devildom and force them into a harem of anime demon men. It's confirmed, your source is me, thank you very much.
